Application September 22,

1 Claim.

The present invention relates to a harrow tooth and the object of theinvention is to provide a more simple and efiicient construction than isdisclosed in my Patent No. 1,950,834.

The novelty of the improved structure resides in the manner in which thetooth is mounted.

With the above and numerous other objects in view as will appear as thedescription proceeds, the invention consists in certain novel features 0of construction and in the combination and arrangement of parts as willbe hereinafter more fully described and claimed.

In the drawings:--

Figure 1 is a side elevation of the tooth showing the same mounted.

Figure 2 is a sectional view therethrough, taken vertically.

Figure 3 is a similar view but showing the tooth in a differentposition.

Figure 4 is a front elevation.

Figure 5 is a perspective view of the tooth per se.

Figure 6 is a disassembled view showing the bar, the bolt and nut.

Referring to the drawings in detail it will be seen that the numeral 5denotes the bar which is of channel-shaped construction. The bolt 6 isinserted through the upper juncture of the bar in a diagonal manner andhas the nut "l associated therewith.

The tooth is denoted by the numeral 8 and the upper end thereof mergesinto convolutes 9, and the last convolute has a notch H3 formed therein.The convolutes 9 are adapted to be disposed about the bar 5. The boltextends through the 1936, Serial No. 102,033

1 and 2 indicates direc- It is thought that the construction, utilityand advantages of this invention will now be quite apparent to thoseskilled more detailed description in this art without 21. thereof.

The present embodiment of the invention has been described inconsiderable detail merely for the purposes of exemplification since inactual practice it attains enumerated as the features of advantagesdesirable in the statement of the invention and the above description.

It will be apparent that changes in and in the combination and arofconstruction,

the details rangement of parts may be resorted to without departing fromthe spirit or scope of the invention as hereinafter claimed orsacrificing any of its advantages.

What is claimed is:- A device of the class described, including incombination, a bar, a tooth, convolutions formed on the tooth, the lastconvolution free end portion adjacent the being bent backwardly towardthe last convolution in spaced relation thereto and having its centralportion curved inwardly with the free end convolution, a bolt extendingbent inwardly abutting the last through the bar and being slidable inthe space formed between the free end portion and the last convolutionfor adjustably securing the device on the bar.
